Description

Technical Field

[0001] The utility model relates to the technical field of preheating of hot pressing machines, and particularly relates to a preheating structure of a hot pressing machine. Background Art

[0002] A hot pressing machine is an important industrial equipment, which is widely used in industries such as plastics, rubber, and composite materials. It processes raw materials into products with specific shapes by heating and pressing.

[0003] In modern production processes, pipeline production is usually adopted. The coiled aluminum film is unrolled through an unrolling device, and then sent into the working area of the hot pressing device through a feeding component for hot pressing. However, during the feeding process, the edge of the fed aluminum film will be wrinkled due to rapid temperature rise, which affects the production quality of balloons. Secondly, since there are dust and other particles on the surface of the aluminum film roll, these particles will affect the heat sealing processing quality of the aluminum film balloon, and even cause defective products such as air leakage.

[0004] The existing patent (publication number: CN215237090U) discloses a hot pressing forming device for producing aluminum film balloons, including a frame and a hot pressing forming mechanism arranged on the frame. It is characterized in that: a preheating mechanism for preheating the aluminum film is arranged on the output side of the hot pressing forming mechanism. The preheating mechanism includes a mounting frame arranged on the frame, an upper rotating roller, a lower rotating roller, and an electric heating tube. The upper rotating roller and the lower rotating roller are both rotatably arranged on the mounting frame, and the upper rotating roller and the lower rotating roller are longitudinally spaced. The upper rotating roller is driven to rotate by a first motor installed on the mounting frame. The electric heating tube is fixedly sleeved on the upper rotating roller and rotates together with the upper rotating roller. This utility model has strong practicability and is easy to promote.

[0005] In view of the above problems, the existing patent gives a solution. However, there are certain limitations in the use of the above solution. During the preheating process of different materials, it is not convenient to adjust the preheating structure according to the size of the materials.

Moreover, some dust and impurities will adhere to the surface of different materials during transportation, which easily affects the preheating efficiency.

[0006] Therefore, a preheating structure of a hot pressing machine is proposed. Summary of the Utility Model
